With the Mac App Store, getting the apps you want on your Mac has never been easier. No more boxes, no more discs, no more time-consuming installation. Click once to download and install any app on your Mac. But if an app you need isn’t available from the Mac App Store, you can use DVD or CD Sharing. This convenient feature of OS X lets you wirelessly “borrow” the optical drive of a nearby Mac or PC. So you can install applications from a DVD or CD and have full access to an optical drive without having to carry one around.
